The Eastern practice of yoga has become a modern-day symbol of peace, serenity and well-being in the West. An estimated 1 million British and more than 20 million Americans practice yoga, according to the 2012 Yoga in America study, with practitioners spending more than £6 billion a year on yoga-related products and classes.

The mind-body practice is frequently heralded for its ability to reduce stress and boost well-being, but it also offers wide-ranging physical health benefits that rival other forms of exercise. While the scientific research on yoga’s health benefits is still young, here’s what we know so far about its potential effects on the body.

After Class.

Improved Brain Function.

Just 20 minutes of Hatha yoga – an ancient form of the practice that emphasizes physical postures rather than flow or sequences – can improve cognitive function, boosting focus and working memory. In a University of Illinois study, participants performed significantly better on tests of brain functioning after yoga, as compared to their performance after 20 minutes of vigorous aerobic exercise.

Lower Stress Levels.

Yoga’s stress-busting powers may come from its ability to lessen the activity of proteins that are known to play a role in inflammation, according to a study published last year from University of California, Los Angeles researchers.

Alter Gene Expression.

A small Norwegian study suggested that yoga’s many healthy benefits might come from its ability to alter gene expression in immune cells.

Increased Flexibility.

A recent Colorado State University study found that Bikram yoga – a form of yoga in which a series of 26 postures are performed for 90 minutes in a heated room – is linked with increased shoulder, lower back and hamstring flexibility, as well as greater deadlift strength and decreased body fat, compared with a control group.

After A Few Months.

Lower Blood Pressure.

People with mild to moderate hypertension might benefit from a yoga practice, as a study from University of Pennsylvania researchers found that it could help to lower their blood pressure levels. Researchers found that people who practiced yoga had greater drops in blood pressure compared with those who participated in a walking/nutrition/weight counseling program.

Improved Lung Capacity.

A small 2000 Ball State University study found that practicing Hatha yoga for 15 weeks could significantly increase vital lung capacity, which is the maximum amount of air exhaled after taking a deep breath. Vital lung capacity is one of the components of lung capacity.

Improved Sexual Function.

A 2009 Harvard study published in the The Journal of Sexual Medicine showed that yoga could boost arousal, desire, orgasm and general sexual satisfaction for women. Yoga can also improve women’s sex lives by helping them to become more familiar with their own bodies, according to a review of studies published in the Journal of Sex and Marital Therapy, as reported by CNN.

Reduced Chronic Neck Pain.

A German study published in The Journal of Pain showed that four weeks of practicing Iyengar yoga (a type of Hatha yoga that stresses proper alignment and the use of props) is effective in reducing pain intensity in adults suffering from chronic neck pain.

Anxiety Relief.

A 2010 Boston University study showed that 12 weeks of yoga could help to reduce anxiety and increase gamma-aminobutyric (GABA) levels in the brain (low levels of GABA have been linked with depression and anxiety disorders).

Relief from Chronic Back Pain.

Researchers at West Virginia University found Iyengar Yoga to be more effective in reducing pain and improving mood than standard medical treatment among those with chronic lower back problems.

Steady Blood Sugar Levels in People with Diabetes.

Adding yoga to a typical diabetes care regimen could result in steady blood sugar levels, according to a 2011 Diabetes Care study. Reuters reported that just three months of yoga in addition to diabetes care resulted in a decrease in body mass index, as well as no increases in blood sugar levels.

Improved Sense of Balance.

Practicing a yoga program designed for older adults was found to improve balance and help prevent falls in women over 65, according to a 2008 Temple University study.

After Years.

Stronger Bones.

“We did a bone mineral density (DEXA) scan, then we taught half of them the yoga, waited two years, and did another scan,” Fishman previously told The Huffington Post. “And not only did these people not lose bone, they gained bone. The ones who didn’t do the yoga lost a little bone, as you would expect.”

Healthy Weight.

Researchers from the Fred Hutchinson Cancer Research Center in Seattle found an association between a regular yoga practice and decreased weight — or at least a maintained weight — among more than 15,000 healthy, middle-aged adults.

Yoga Lily

Lili has been studying and practising yoga in China & UK for 20 years, and teaching since 2007 (7 years in the UK). She draws inspiration from her training within established, classical yoga systems that focus on alignment, hatha vinyasa in its gentler form, yin, yin/yang, and restorative yoga styles, pranayama and meditation; blending the roots of Chinese healing traditions into a more holistic practice.
For her, practice covers not just the physical aspects of yoga but also aligning and unblocking the bodies meridian energy pathways to release Qi energy (prana) which flows through the bodies energy highway, bringing the mind, body and spirit back into balance.
“I am continually humbled by my students and teachers, my aim is always to teach from the heart and from the idea that yoga is the art of living, listening and learning, to embody this deeply spiritual tradition”
